Keep that umbrella handy -- this soggy Tuesday could stretch into the early evening, says Storm Team 4 meteorologist Tom Kierein.

We can expect pockets of moderate to occasionally heavy rain through the afternoon, which could cause some ponding in low-lying areas.

Rockville Pike was slightly flooded as of 11 a.m., with drivers cautioned to proceed carefully.

Downed wires and a pole fire were attributed to a blown transformer at Rockville Pike and Nicholson Lane in North Bethesda. That knocked out power to about 900 customers and 25 traffic lights. A generator was set up at that intersection to run the traffic lights until power was restored.

Metro temporarily closed the Dupont Circle station around 9:10 a.m. for what they called a weather-related escalator malfunction, with the stopped escalators likely too slippery to walk down. The station reopened a half-hour later.

The rain is expected to taper off into light passing showers this afternoon and should end completely by mid-evening, Kierein said.

However, Tuesday night's Nationals game -- scheduled to start at 7:05 p.m. -- could be delayed as a result. If you're going, remember to bring a poncho and a towel to dry off your seat!

The bright side? Wednesday should NOT be more of the same, Kierein said. You can expect to experience a touch of summer, with warm and humid weather and temps reaching the mid-80s by Wednesday afternoon.
